curl_setopt($ch, CURLOPT_POSTFIELDS, $postfield); //设置POST提交的字符串
1.其中这里的 CURLOPT_POSTFIELDS是保存在http的Header中还是哪里？
2.与网页中表单Form的Post方式有何区别？
我是做DELPHI的，然后IDHTTP控件模拟网页的POST方式，但与PHP的这个好像有点区别。
$postfield这里的只看到有指定值，没看到有指定NAME属性哎。
回复讨论(解决方案)
$postfield 是将表单所有的name和value按照键值对方式用&连接起来的字串
依据http协议，它不属于header，而是正文（与header部分理应有\r\n\r\n隔开）
$postfield 是将表单所有的name和value按照键值对方式用&连接起来的字串
依据http协议，它不属于header，而是正文（与header部分理应有\r\n\r\n隔开） POST方式的话是用换行隔开的吗？如果不指定他的NAME只有一个VALUE提交上去是啥结果呀？
合法的格式应该是 类似'para1=val1¶2=val2&...'或使用一个以字段名为键值，字段数据为值的数组
你只传value,那么目标页面就无法获取你提交的值咯。
无论什么方式，提交就是发送字串而已，一般post是由浏览器做这个事
curl只是模拟post，只是把一些参数组织起来发送，代替了浏览器
你两个delphi月排行第一，应该也做过socket吧，socket不就是把字串按照http规范拼接起来发送么？
我都说了是键值对，就必然有name了
name=abcdefg&password=123456...
只有value，结果就是服务端找不到所需要的变量?
